[Leica] cosmic (gamma) rays and sensors

[lmdmd at att.net (Leland Deane)]

I heard a disturbing blurb on a tech podcast today about the ability of 
cosmic/gamma rays------from airplane travel-----to effect sensors so that 
some pixels over time get either 'full on' or 'full off'. It has not 
received much attention because the loss of a 'few hundred' pixels doesn't 
effect the image output because the software just uses info from the 
adjacent pixel. The camera companies are concerned enough, however, to 
transport large batches of sensors by ship only. Ordinarily, I wouldn't care 
too much but I grow increasing protective of my M9 and monochrome and am 
planning to take both abroad next month. I'm thinking about using old 
fashioned lead film protector bags which are still available. A web search 
has not been that helpful for info so I'm hoping the LUG collective wisdom 
knows something.
Cheers,
Leland
